14 cheapest boilers

Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

In many regions of Russia in winter, the air temperature drops significantly below zero. Therefore, in houses, workshops and workshops, heating is indispensable. The most popular at present are closed circulation systems, in which water or antifreeze plays the role of a coolant. Boilers are used to heat the liquid. Since heating devices cost a lot of money, consumers start choosing cheap models. Our experts will help you find efficient devices among budget boilers.

Recommendations for choosing a heating boiler

Fuel type. The most important criterion for choosing a boiler is the type of fuel that will be used as an energy source.

1. Natural gas remains the most affordable and convenient option for heating residential buildings and industrial facilities. The gas boiler must be equipped with security systems to exclude the possibility of poisoning or explosion in case of malfunction.
2. In those regions where there is no gas main, solid fuel boilers have to be installed. They can operate on wood, pellets, coke, peat and coal. The only drawback is the impossibility of automating the process. Solid fuel quickly burns out, after which cleaning and the subsequent laying of a new batch of firewood is required.
3. Electric boilers are considered the simplest and most environmentally friendly. Modern models can be controlled remotely, but not every electrical network can withstand the load of a powerful heating element. And the cost of electricity is still high in Russia.
4. Liquid fuel boilers are inferior in popularity to gas and solid fuel models. Such devices are quite expensive, in addition, you will have to purchase and bury a large container for storing diesel fuel in the ground.

Thermal power. All boilers have a certain maximum heating output. This indicator allows you to select the device taking into account the area of ​​the house or workshop. Experts advise sticking to a simple formula. For heating a room with an area of ​​10 sq. m with a ceiling height of 2.5 m, 1 kW of thermal energy is required. But since losses are inevitable during heat transfer, it is better to purchase a boiler with a power reserve (15-20%).

Heat exchanger material. The heat exchanger is most exposed to the aggressive effects of fire and water. Manufacturers use several materials for the manufacture of this critical part.

1. The cheapest boilers are equipped with a steel structure. Their service life is limited to several years due to rapid corrosion.
2. Heat exchangers made of stainless steel are considered more tenacious. They are not afraid of corrosion, but they are expensive.
3. Copper assemblies have good heat transfer and low weight. They are compact but expensive and shock-resistant.
4. Cast iron compares favorably with other materials in corrosion resistance, reliability and durability. Only if the heating is uneven can the heat exchanger crack.

We have selected the 14 cheapest boilers for the review. You can buy them in specialized stores in our country. When allocating seats, the editorial staff of the magazine proceeded from the opinions of experts, taking into account the opinions of Russian consumers.
